The SPI examination fee is $225 USD, which includes a $100 USD non-refundable processing fee. If you take an ARDMS examination at an international test center (outside the U.S., Canada, and Mexico), you will be charged an additional non-refundable $100 USD fee when you schedule your examination. This fee is subject to change without notice.

Prerequisites
If the SPI examination is the first examination you are applying for, you can choose to apply under the SPI Examination Requirement pathway or you can apply under a prerequisite. The SPI Examination Requirement just requires completion of a physics class or a physics review course (click below for specific details). However, if you can meet the requirements of an existing prerequisite (1 through 5), you are encouraged to do so as future application processing will be faster and easier.
You must wait 60 days before you can retake the SPI examination if you do not pass it however, you are welcome to reapply after 3 days.

Prepare With an SPI Practice Test
Taking a practice test or two is a great way to prepare for your actual examination. We offer two online versions of the SPI Practice Test — SPIa and SPIb — that simulate the computer interface used in the actual test center environment. The SPI practice test review is comprised of 30 sample questions and is 30 minutes long.
The two distinct versions are equivalent in difficulty and content coverage. Note that if you take either test more than once, the questions will be the same.
After you complete a practice test, you will be emailed a report that shows the number of questions you answered correctly. While the report is an indication of your knowledge, the practice tests results should not be used to predict how well you will perform on the actual examination at the test center.
